Summary: | A sensing system and method are provided. The sensing system includes a sensor unit that is configured to output a voltage having a magnitude that corresponds to a detected physical quantity and an amplification unit that is configured to amplify a magnitude in the output of the sensor unit to a constant gain. An offset removal unit is configured to remove a direct current (DC) offset from an output amplified by the amplification unit to generate a first detection signal. An inversion circuit unit is configured to invert the first detection signal to generate a second detection signal. A microcomputer is configured to then calculate the physical quantity detected by the sensor unit based on the first detection signal and the second detection signal. |
